Kolkata: P Chidamabaram's statement that intra-party clashes in the last 6 months in West Bengal was a matter of concern, led between UPA partner Trinamool Congress on Friday to claim that it was a 'conspiracy' ahead of the Presidential polls, while ally Congress agreed that the Union Home Msinister was right.

"There is a conspiracy against the Trinamool Congress prior to the Presidential election and Chidambaram's statement is backed by motivation," state panchayat minister and senior Trinamool Congress leader Subrata Mukherjee told reporters.

"Chidambaram is used to making such statements. He should have been careful in making such statements and should have ascertained facts," Mukherjee said at the media centre in the assembly premises.

On the other hand, agreeing with Chidambaram, senior Congress leader Abdul Mannan said "West Bengal now accounts for 12 percent of the total crime committed in the country. The crime rate is on the rise in the state."

Alleging that there was not much change in the state after 'parivartan' (change) was ushered in last year, Mannan, in an oblique reference to Chief Minister Mamata Banerjee, said, "she has been speaking against the Centre because of frustration that her master stroke against the Congress leadership on the presidential election failed."

He also pointed out that Chidamabaram had said on Thursday that Pranab Mukherjee was sure to get 65 percent votes in the Presidential election without Trinamool Congress support.
